Since our last post, our team has moved an hour south to the small village of Weyakwin, where the Philion Fire burned last year. There is a lot of logging Weyakwin, and we are very interested in the interactions between fires and logging. We are comparing burned forests that grew back after people cut trees, to those that grew back after an earlier forest fire.

We believe there could be differences between the two in burn severity and the amount of carbon released by the fire. When a plot is harvested for lumber, the logs are removed but the soil remains. This is the opposite of burned areas, where fire burns into the soils but a lot of the trees remain standing, albeit charred. To study these differences, we are searching for areas of burn and harvest origin that are about the same age. We have seen some very young burned sites, many were less than 10 years old when they burned. This is surprising since forests in boreal regions typically burn when they are 50 to 100 years old. …read more
